当代中国公民参与新闻传播的热情空前高涨。同时，在新闻舆论场域也出现了一些伦理缺失、新闻失范的乱象，并导致一系列的国家法规动作。论文的问题是：来自西方的新闻专业主义及其媒介伦理是否能够在当下中国发挥纠偏除弊的积极作用？其意义和价值又该如何引进？论文审视了西方新闻专业主义和媒介伦理与当代中国的关系、新闻专业主义引进中国后的困境、公民参与报道给中国媒介伦理带来的挑战。论文认为，新闻专业主义和媒介伦理可能促进中国新闻传播事业和政府-媒介关系的发展，但媒介改革仍面临困难和问题。

In the age of new communication technologies, the motivation of Chinese citizens to express their appeals has gained ever-more momentum than before. Meantime, there are more occurrences of lack of ethics and journalism anomie which lead to a series of regulation by the central government. This paper discusses the questions that if the journalistic professionalism and media ethics from the west would help eliminate the journalism anomie in current China; and how to introduce professional values and meanings deeply rooted in western to China. The paper mainly examines the relationship between the western journalistic professionalism and contemporary China, the problems and dilemmas in China’s journalism system after the introduction of journalistic professionalism, and the challenges to media ethics brought by the public participation in journalism. The paper argues that the western journalistic professionalism and media ethics have positive meanings and normative values in China; while China still faces many difficulties in its journalism reform and professional media ethics.
